Wendy I agree, Thank you!Wendy Wagner - Hey, what a neat surprise success!
Alexandra Clark - Mounding saw dust, no matter how deep is a soft and easy thing for tough crab grass rhizomes to sprout through. My suggestion which I have used successfully to address invasive plants in the garden is to lay down dry cardboard on those paths, then wet the top a little and add leaf litter and then wood mulch or saw dust. Water down well. Whenever you see a patch breaking down, simply add another layer of cardboard (sun/heat/moisture barrier) and you should be good to go. You may have some side growth of the plants but that can be easily taken care of by running a flat spade into the earth, cutting the rhizomes and flicking the shoots upside down.
You could also do a two step process where you lay black plastic over your paths with rocks to weight it down and leave it like that for 6 weeks. It will solarize the ground underneath and you can then build your cardboard paths.
I have about 28 large brown cardboard pizza boxes stacked in my garage waiting to go into paths in the back yard. I am dealing with a big patch of poison ivy first..yeck!
William Bronson - I like the way you are looking at things! Maybe you could introduce clover to crowd out the grass? Sawdust and wood chips mixed with soil are said to lead to nitrogen deficiencies. I had a thought a while ago to do this on purpose to advantage nitrogen fixers like clover, seeing as every clover patch I start us overwhelmed by "weeds"
webpage Now, while most people limit the concept to evolutionary biology, I see the process occurring everywhere all the time. (Silly geologist, always got my head in the ground.) If we remove the new species evolutionary aspect and replace it with any other natural process, well this is exactly how Nature works. Nature wants a balance, an equilbrium, until there is a disturbance, which induces a little chaos until a new balance is found.noun 1. theory of, Biology. a hypothesis holding that the evolution of species proceeds in a characteristic pattern of relative stability for long periods of time interspersed with much shorter periods during which many species become extinct and new species emerge. Also called punctuationalism.
Let it never be said that ol’ Rocky doesn’t give em’ a chance to speak up for themselves. The forums at permies.com are a great place to learn and ask about permaculture from someone who isnt such a disenchanted, pessimistic asshole as myself.

and now several minutes later...Wow! I just opened my own mental "Can O' Worms" - (And how ironic is that phrase, now seen through a Permaculture lens)a design for a permies playground
